Beschreibung

The LimeSDR Mini is a low-cost software defined radio board. LimeSDR-Mini development board provides a hardware platform for developing and prototyping high-performance and logic-intensive digital and RF designs using Intel’s MAX 10 FPGA and Lime Microsystems transceiver. In comparison to the Lime SDR, the Mini has two channels instead of four and SMA connectors instead of micro U.FL connectors. Since it uses the same LMS7002M radio transceiver, it doesn't luck any power.

Free & Open Source

The LimeSDR Mini is a free and open source project made in collaboration with the Myriad-RF project page project. As the full-size LimeSDR, it uses the host-side open source software called LimeSuite. A big part of the LimeSDR ecosystem is the Snappy Ubuntu Core app store. LimeSDR and LimeSDR Mini use the same drivers and APIs.
